I am modeling some off-the-wall scenarios to try out with a game engine.
One idea is trying to make a planet where some weird catastrophic incident has creates a funny shaped planet. I'm hoping to take advantage of differences in gravity, seasons, etc only I'm not sure this is physically possible in the first place.
For instance if two earth-sized planets collide being made purely of iron a star happens to forge in a crystalline structure favorable for impacts, what could be expected? Perhaps one of the objects could have been constructed by intelligent life and have a more specific structure if helpful.
What conditions could allow for a situation where two planetary objects have collided and maintain most of their individual shapes, at least temporarily?
